BcubeGmsh.jl

Implementation of Bcube IO interface for Gmsh format. Checkout the relative Bcube documentation for more infos.

For now, only the read_file interface is implemented.

Basic usage

using Bcube
using BcubeGmsh

mesh = read_mesh("output.msh")
@show ncells(mesh)

Mesh generators

This project also contains some "common" mesh generators. Here is a non-exhaustive list:

• gen_line_mesh( output; nx = 2, lx = 1.0, xc = 0.0, order = 1, bnd_names = ("LEFT", "RIGHT"), n_partitions = 0, kwargs... )
• gen_rectangle_mesh( output, type; transfinite = false, nx = 2, ny = 2, lx = 1.0, ly = 1.0, xc = -1.0, yc = -1.0, order = 1, bnd_names = ("North", "South", "East", "West"), n_partitions = 0, write_geo = false, transfinite_lines = true, lc = 1e-1, kwargs... )
• gen_hexa_mesh( output, type; transfinite = false, nx = 2, ny = 2, nz = 2, lx = 1.0, ly = 1.0, lz = 1.0, xc = -1.0, yc = -1.0, zc = -1.0, order = 1, bnd_names = ("xmin", "xmax", "ymin", "ymax", "zmin", "zmax"), n_partitions = 0, write_geo = false, transfinite_lines = true, lc = 1e-1, kwargs..., )
• gen_sphere_mesh( output; radius = 1.0, lc = 1e-1, order = 1, n_partitions = 0, kwargs..., )
• gen_cylinder_mesh( output, Lz, nz; radius = 1.0, lc = 1e-1, order = 1, n_partitions = 0, kwargs..., )
• gen_mesh_around_disk( output, type; r_in = 1.0, r_ext = 10.0, nθ = 360, nr = 100, nr_prog = 1.05, order = 1, recombine = true, bnd_names = ("Farfield", "Wall"), n_partitions = 0, kwargs... )
• gen_disk_mesh( output; radius = 1.0, lc = 1e-1, order = 1, n_partitions = 0, kwargs... )
• gen_ring_mesh( output; r_int, r_ext, lc = 1e-1, transfinite = false, nr = 0, nθ = 0, order = 1, n_partitions = 0, kwargs..., )

Development instructions

To run the tests, git lfs must be present on your system, and you must fetch the concerned files:

git checkout foo
git lfs install
git lfs pull
